Gregor Mendel was a pioneer in establishing the basic pattern of genetic inheritance. After Mendel, other scientists turned investigated of what a gene is made.
1910 - Thomas Hunt Morgan showed that genes are on chromosomes.
1940s and 1950s - Experiments isolated DNA as the basic genetic material.
1951 - Rosalind Franklin obtained sharp X-ray photographs of DNA.
1953 - James D. Watson and Francis Crick discovered that DNA’s structure with a double helix.
This marked the beginning of a new era. Today, scientists have discovered the secrets of the genetic code and can manipulate genes through genetic engineering.
